Invasive Plant Patrol Workshops

>> Please see our Home page for more 2020 season Information <<

Manual Control Training Webinar(Part 1) – Thursday, June 4 – 9AM to Noon

This webinar will provide attendees with:

  • An overview of IAP management in Maine;
  • An introduction to the three primary manual control methods: manual harvesting (or hand pulling); benthic barriers; and diver assisted suction harvesting (DASH); discussion will cover techniques, gear, and circumstances to which each control method is best suited;
  • An introduction to Maine’s most unwanted invasive aquatic plants;
  • A brief discussion of permit and reporting requirements.

This training is mandatory for those who wish to become a certified member of Maine’s IAP Manual Control Team and/or participate in IAP control programs that receive State funding.  

Due to coronavirus, Part Two of this training (in-lake instruction and practice) will be led locally, by certified control project leaders. More information to be announced.


Invasive Plant Patrol Workshops & Certification: No live, in-person IPP workshops will be held in 2020, but an IPP certification course will be offered online. The course will be comprised of three webinars. Part 1 will provide a general introduction to the threat of aquatic invaders; Part 2 will dive into Aquatic Plant ID; Part 3 will provide guidance for conducting an invasive plant screening survey, including tools and techniques.  Each section will be followed by an optional online quiz (mandatory only for those who wish to become certified).  In the final stage of certification, participants will collect several plants on their own, and then attend one live plant idea Zoom session for feedback on ID’s and/or guided identification.

Advanced IPP Training: Three Advanced Plant ID webinars will be offered this summer covering: milfoils, bladderworts, and common pondweeds.

Other IPP Offerings: Unable to reach out to you physically, in workshops and events, we will be doing everything we can technologically to provide existing and new volunteers with the knowledge, guidance and encouragement needed to continue to monitor Maine waters for the presence of aquatic invaders. Here are some examples:

> We’re producing a GoPro-style video series called Lessons from the Littoral Zone, to be posted to YouTube and Facebook, (some possibly as live events)

> LSM will host an IPP Leaders’ Zoom Room, occasional check-in and problem solving sessions for those leading lake teams and regional efforts

> IPP Leaders Page will be completely overhauled and updated with a section for team posts.

Suspicious Species ID: LSM will continue to provide this important free service for volunteers and the general public. Though plants may still be sent to or dropped off at our Auburn offices, we are encouraging people to make the switch to online photo submission through email (additional electronic submission options will be available in the near future). We will also be holding regularly-scheduled, interactive Zoom-based plant ID sessions, and offering special sessions for teams by appointment.

More information will be posted soon; please check back.

Our Mission

The Mission of the Lake Stewards of Maine (LSM) is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. LSM trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, LSM volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities.


LSM is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 40 years, trained volunteers throughout Maine have donated their time so that we may all learn more about one of Maine’s most beautiful and important resources — our lakes.
